Basal Metabolic Rate is the energy required to maintain the body’s normal function, it is a measure of how much energy is used by someone who is at rest. To calculate your BMR we are going to use the Schofeild equation. This equation takes into account someone’s age, weight , it is very accurate for the average adult.

Schofeild Equation

MENS :

10 - 17 years BMR = 17.7 x W + 657

18 - 29 years BMR = 15.1 x W + 692

30 - 59 years BMR = 11.5 x W + 873

60 - 74 years BMR = 11.9 x W + 700

WOMENS :

10 - 17 years BMR = 13.4 x W + 692

18 - 29 years BMR = 14.8 x W + 487

30 - 59 years BMR = 8.3 x W + 846

60 - 74 years BMR = 9.2 x W + 687

Key: W = Body weight in kilograms

To calculate your weight from pounds into kilograms you have to divide by 2.2, for example if you weigh 140 pound you would divide 140 by 2.2 which would give you 63.6.

conversion table:

100 pound ÷ 2.2 = 45.4kg

110 pound ÷ 2.2 = 50kg

120 pound ÷ 2.2 = 54.5kg

130 pound ÷ 2.2 = 59kg

140 pound ÷ 2.2 = 63.6kg

150 pound ÷ 2.2 = 68.1kg

160 pound ÷ 2.2 = 72.7kg

170 pound ÷ 2.2 = 77.2kg

180 pound ÷ 2.2 = 81.8kg

190 pound ÷ 2.2 = 86.3kg

200 pound ÷ 2.2 = 90.9kg

210 pound ÷ 2.2 = 95.4kg

220 pound ÷ 2.2 = 100kg

Here is an example of how to work out your Basal Metabolic Rate. Lets say you are a 24 year old 140 pound bodybuilder so we use the equation
